A deck of clouds assisted firefighters dealing with heat around the massive La Tuna Fire Sunday, but winds associated with the leftovers of a tropical storm alarmed the crews surrounding tha massive blaze.

There were 1,061 firefighters battling what tghe mayor called the biggest brush fire in the city of Los Angeles history, as crews worked on pockets of unburned brush within the Friday, iow churning through the norther end of the Verdugo Moutains in its third day.

The estimate of burned acres remained at 5,895 acres.

“There is (still) a lot of fuel out there left to burn,” said Los Angeles Fire Department Chief Ralph Terrazas, during a 10 a.m. news conference at Hansen Dam in Lake View Terrace. The fire remained at 10 percent contained with the effort of 206 engine companies, nine helicopters, five water tenders, four bulldozers, 12 hand crews and nine ambulances.

“We are going to get an update on the containment percentage by the end of the day. That is our goal,” Terrazas said.

And the biggest concern in battling the blaze still remains the weather, he said.

“In terms of weather, that is our number one concern. Sunday and the rest of the week, we believe that the weather will become more favorable. Sunday we’re looking at moderate heat impact, isolated thunderstorms with a very slight chance of showers, temperatures 90 and 94 degrees.

“Winds with three to four miles per hour with gusts at 12 (miles per hour) and that can change at a moment’s notice and the wind can accelerate very quickly,” Terrazas said.

There were two firefighters taken to hospitals during the second day of the fire for heat-related illnesses. Their conditions were stable, he said.

Three homes have been destroyed and one was damaged. “We believe two of three had no brush clearance,” Terrazas said. “So I can’t emphasize enough the importance of a minimum — within L.A. city — a minimum of 200 feet brush clearance, that’s brush from your home. If there is no defensive space we cannot protect your house.
